It needs also a new go + re-vendoring. I think we can add those to #261

The go.mod that needs update is located at csi-test repo. So I think it cannot be fixed by PR in this repo.

[pohly]

I agree that the failure in pull-kubernetes-csi-release-tools-csi-test can be ignored. That job is intentionally declared as "not required". The vendoring issue needs to be sorted out when updating csi-release-tools in the csi-test repo.

I don't know what Trivy is complaining about. It seems to block merging?

[huww98]

It seems my PR #261 is not triggering Trivy, because it is awaiting approval. So, I can work around this 😂

I've rebased #261 onto #264 .
